[PATCH 06/14] tools: Separate interface related completers into a file

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Mixing all completers in one file does not support
maintainability. Separate those completers which relate to
interfaces (e.g. they complete various interface aspects)
into virsh-completer-interface.c
